标准摘要
[中文适用范围]： ISO 10705 的这一部分规定了通过将样品与适当的宿主菌株一起孵育来检测和计数感染脆弱拟杆菌的噬菌体的方法。 该方法适用于各种水、沉积物和污泥提取物，必要时可稀释后使用。 在噬菌体数量低的情况下，可能需要预浓缩步骤，为此制定了单独的国际标准。 该方法也适用于贝类提取物。 注：希望尽可能广泛地采用国际标准。 ISO 10705 的这一部分包括对替代程序的参考，这些替代程序避免了对发展中国家可能不易获得的昂贵材料或设备的需求。 使用这些替代方案不会影响该方法的性能。 [外文原描述]： This part of ISO 10705 specifies a method for the detection and enumeration of bacteriophages infecting Bacteroides fragilis by incubating the sample with an appropriate host-strain. The method is applicable to all kinds of water, sediments and sludge extracts, where necessary after dilution. In the case of low phage numbers, a preconcentration step may be necessary for which a separate International Standard has been developed. The method is also applicable to shellfish extracts. NOTE It is desirable for International Standards to be adopted as widely as possible. This part of ISO 10705 includes reference to alternative procedures which obviate the need for expensive materials or equipment which may not be readily available in developing countries. Use of these alternatives will not affect the performance of this method.
